The updated world average of the branching ratio of \(B_s \rightarrow \mu ^+ \mu ^-\)  which is \(( 2.93 \pm 0.35 ) \times 10 ^{-9} \)  [1]}.

Recently updated differential branching fraction measurements of \(B_s \rightarrow \phi \mu ^+ \mu ^-\)  by LHCb
in various \(q^2\)  intervals [2]}.

The differential branching ratios of \(B^0 \rightarrow K^{*0} \mu ^+ \mu ^- \)  [3]}, [4]}, [5]}, \(B^{+} \rightarrow K^{*+}\mu ^{+}\mu ^{-}\) , \(B^{0}\rightarrow K^{0} \mu ^{+}\mu ^{-}\) and \(B^{+}\rightarrow K^{+}\mu ^{+}\mu ^{-}\)  [6]}, [4]} in different \(q^2\)  bins.

The branching fraction of inclusive decay mode \(B \rightarrow X_{s}\mu ^{+}\mu ^{-}\)  [8]} where \(X_{s}\)  is a hadron containing only one kaon is included in the fit in the low and high-\(q^2\)  bins.

The longitudinal polarisation fraction \(f_L\) , forward-backward asymmetry \(A_{FB}\)  and observables \(S_3\) , \(S_4\) , \(S_5\) , \(S_7\) , \(S_8\) , \(S_9\)  in the decay \(B^0 \rightarrow K^{*0} \mu ^+\mu ^-\) 
in various intervals of \(q^2\) , as measured by the LHCb collaboration in 2020 [9]}, along with their experimental correlations.

The angular observables \(f_L\) , \(P_1\) , \(P^{\prime }_4\) , \(P^{\prime }_5\) , \(P^{\prime }_6\)  and \(P^{\prime }_8\)  in \(B^0 \rightarrow K^{*0} \mu ^+\mu ^-\)  decay measured by ATLAS [10]} and \(P_1\) , \(P^{\prime }_5\)  measured by CMS [11]}.
The measurements of \(f_L\)  and \(A_{FB}\)  by CDF and CMS collaborations are also included [4]}, [5]}.

The full set of angular observables for \(B^+ \rightarrow K^{*+} \mu ^+\mu ^-\)  decay mode was determined for the first time by LHCb in 2020 [14]}. Here, we consider results for \(F_L\)  and \(P_1 - P_8 ^{\prime }\)  optimized angular observables, along with their experimental correlation [14]}.

We include the \(CP\) -averaged observables \(f_L\) , \(S_3\) , \(S_4\)  and \(S_7\)  in \(B_s \rightarrow \phi \mu ^+\mu ^-\)  decays measured by the LHCb in 2021 with the available experimental correlations [16]}.
